Public bug reported:

In Ubuntu 13.10, there is a conflict between notification-daemon and
notify-osd when running a GNOME Flashback session.

The following two issues are correlated:

1) When a notification arise, there is a mix of GNOME 3-like and Ubuntu
notification styles (graphically). It can be easily reproduced with the
notify-send command.

2) The events like volume up/down/mute no longer shows a notification.
To reproduce, just use the keyboard's volume buttons, or scroll on the
sound indicator in the gnome panel.

After some investigation, I found that killing the process /usr/lib
/notification-daemon/notification-daemon fixes the problem. After that,
the notifications uses only the Ubuntu's style and the volume
up/down/mute notifications appears again.

The gnome-session-flashback 3.6.2 package depends on the notification-
daemon 0.7.6 package, which autostarts the notification-daemon process
when running a GNOME Flashback session. I could manage to disable it by
editing the file /etc/xdg/autostart/notification-daemon.desktop. As a
workaround, I changed the line:

    AutostartCondition=GNOME3 unless-session gnome

To:

    AutostartCondition=false

Something should be done so that GNOME Flashback uses only one
notification system, either Ubuntu one or notification-daemon, but not
both at the same time. Moreover, if it is decided to use notification-
daemon, the missing notifications mentioned above (volume...) should be
fixed.
